To all whom it may concern lBe it known that `1, FREDERICK G. Ban, a

citizen of the United States, residing at Columbus, in the county of Franklin and 5, State of Uhio, have invented certain new and useful Improvements in Vaporizers, of which the following is a specification.

Various .endeavors have been made to use kerosene in connection with hydrocarbon engines and by these endeavors, it is. generally conceded that heat is necessary to assist in the volatilization of the oil. ll have reco ized this feature and my invention resi" es essentially ,in the provision of a vaporizing element adapted to be interposed in the eahaustpipe leading from the engine.

lln its preferred form, my invention takes the form of a double walled element having a longitudinal passage therethrough, which element is disposed directly in the exhaust pipe. 1t will, therefore, be apparent that the exhaust gases are in no way impeded l durin their passage outwardly, but the heat there rom is utilized'to assist in the volatilization of the oil, it bein understood that the oilitself is circulated t rough the double walled structure.

ll have also found it desirable4 to pass the incoming air used in forming a combustible ner to slightly increase its temperature, this means preferably taking the form of passing the gases through a secondary chamber termed in the element above referred to.

'lhe preferred embodiment of my invention is shown in the accompanying drawings, in which similar characters o reference designate corresponding parts, and in which: Figure 1 is a view showing my type et vaporizer partly in elevation and partly in section, the remaining portions used in connection therewith being shown somewhat diagrammatically, and, Fig. 2 is a section taken on line 2 2 ot Fig. 1.

1n the use ot kerosene, it has been tound generally necessary to either rovide a structure for initially heating t e kerosene to ed'ect its vaporization, or to start the engine Von solene. 1 have resorted to the latter t at inwhieh ll. have provided a. tank shown tothe lett ot Fig. 1, as comprising a kerosene receptacle 1 and a gasolene receptacle 2. The asolene rptacle isfm direct communication with te et carburetor 3 by t .1

mixture about the exhaust gases, in a man-v any .preferred ...t et the pipe connection t, which l pipe has a shut-od valve 5 disposed therein. en it is desired to start the en'ne, the valve 5 is opened permittin a il of gasolene into the carburetor, it eing understood that the exhaust gases pass out through the exhaust pipe shown at 6. These gases are at a somewhat high temperature and to give the necessary heat when using kerosene, ll have interposed my vaporizer directly haust pipe 6. This vaporizer 1s desiwated generally at 7 and is shown as being in communication with the oil receptacle 1 by means of the p'pe connection 8 also provided with a shut-od' valve 9.

The vaporizer itself comprises an element havin a longitudinal passage 10 entirely theret rough, this element being et a double walled nature. 'llhe wall .11 of the longitudinal passage forms the inner wall of the element, while 12 indicates a second wall somewhat spaced from the first an'd formed concentrically therewith. 'llhe space between these walls is closed bythe solid ends 13 and the chamber thus termed is divided into two compartments 1t and 15 by the provision of a central spacing wall 16. r1`he compartment 15 is rovided with a kerosene inlet opening to w ich the pipe connection 8 is attached and an outlet opening 'to which the outlet pipe 17 is connected, this latter pipe being also provided with a controlling valve 18 vand ultimately leadin to the carbureter 3 by the connection s own at 19. Likewise, thev compartment lit is provided with an air inlet plpe 20'and an outlet pipe 21, the latter leading, as indicated, lto the carburetor 3.

hs has been related, it is desirable to start the engine on gasolene, in which case the valve 5 is opened and the valves 9 and 18 closed, thereby permitting the dow ot gaso- Iene to the carburetor and the incoming air circulated through thecompartment 14: betore entering the carbureter. After the enhaust gases have sulliciently heated the element 7 the valve 5 is closed vand the valves 9 and 18 opened, thereby permitting the dow in the en' of kerosene trom the receptacle 1 throu h the f enters the carburetor, whereby it will be evi v .an exhaust pi e is used, it is obvious that the same will e of particular benefit when used in connection `w1th the exhaust pipes of automobile engines.

` What I claim, is:

v The combination with the exhaust pipe o an internal combustion en e, and a carbureter, of a vaporizer, sai vaporizer comprising an element closed at its' ends an having a longitudinal passage therethrough for the exhaust gases, said element being formed of concentric inner and outer walls thereby forming a chamber therebetween, said inner wall forming the longitudinal passage, a solid spacingwall parallel with the closed ends of said element between said two first named walls dividing said chamber into non-communicating oil and air compartments, separate inlet pipes leading to each of said compartments, and separate outlet pipes for each of said compartments connected to the air and fuel supply openings of said carbureter.

' In' testimony whereof I aiiix my signature in presence of two witnesses.
